appIcon: Scale and fade itself when starting drag

As per design direction, scale and fade the app icon
when starting dragging it, and show it again if the
drop is accepted. Clutter takes care of animating the
rest of icon positions through implicit animations.

Scale and fade the dragged icon while it's being dragged.
